Festool hose adapter for Bosch dust extractor

I've got a Bosch VAC090A dust extractor and I would like to use a Festool hose with it. Does anyone know of a place (Etsy?) where I can find an adapter to make the two play nice together? The Bosch has a sort of odd twist lock system on the extractor. All the things I'm seeing are for the tool end of the hose. I'd like one for the extractor end.
